Search the Book of the Lord

In Isaiah 34:11-15, the prophet revealed how wild animals and plants would take over the places that God judged, and the prophet issued this challenge,
“Search from the book of the LORD, and read:
Not one of these shall fail;
Not one shall lack her mate.
For My mouth has commanded it, and His Spirit has gathered them.”
(Isaiah 34:16)
What the Lord says will happen, happens. He even wants us to check Him out on that. Read the prophecies of the Bible and see whether they have happened, especially the ones dealing with judgment on nations.
Therefore, whatever He promises for the future, you can know will happen.
